The motor 60 works to drive thepaddle 30 to rotate, the rotating direction of the paddle 30 is contrastwith the bracket 20 so that the torsion generated by relative rotationbetween the bracket 20 and the paddle 30 counteracts each other andgenerates downward wind, thereby causing the lift of the boomerang, thelamp strip 70 is illuminated to light. After the boomerang is thrownout, it stably flies in the air according, to the thrown angle, with theworks of the external force, the boomerang flies a distance towards thethrown direction, then because of the gyro effect producing by therotation of the bracket, the flight angle of the boomerang remainsconstant and the boomerang continues to flying in the direction of thatangle. That is to say; users can preset the throwing angle of theboomerang, thereby obtaining different flight trajectories. In theflight process, the boomerang will generate cool lighting effect.

The design focus of the invention is concerned: The boomerang isdesigned as a ball shape and to use the motor to drive the paddle torotate; when the boomerang is thrown out, it stably flies in the air atthe thrown angle. Under the works of the external force thrown, theboomerang flies a distance in the direction thrown, then because of thegyro effect producing by the rotation of the bracket and the paddle, theflight angle of the boomerang remains constant and the boomerangcontinues to flying in the direction of that angle. Users can preset thethrowing angles of the boomerang, thereby obtaining different flighttrajectories, no remote control is required to control the flighttrajectories. Users, can throw the boomerang according to the presettingangles to obtain the presetting flight trajectories, and the boomerangcan achieve to stably and instantly fly in the air. The boomerang issimple in structure and easy to operate. At the same time, with the lampstrip, the boomerang can produce a cool lighting effect.
